It's barely five years old, but the microblogging platform Tumblr already rakes in 15 billion page views every month. With all that buzz, we thought we'd showcase the best accounts out there (with some help from TIME's Tumblr followers, who nominated their own favorites).

It’s Okay to Be Smart

(Readers’ Pick) Think of Joe Hanson as a geeky Batman. (Or maybe Robin.) In his own words, he is a “Ph.D. student/scientist by day, Tumblr science guy by night.” His mission: to share fascinating science stories with the denizens of the Internet. Since April 2010, he has been exploring the far-out aspects of space, biology and technology, stopping every now and then to answer reader questions.

It makes for one of the most easily digestible and entertaining science blogs out there. “I just want to keep reaching more people, teaching more people and being in awe of science along with everyone else,” Hanson says. “That, and maybe becoming Neil deGrasse Tyson’s superhero sidekick.”

With all due respect, there are so many OTHER fabulous Tumblr's out there with great detail and design such as onlybutaglimpse; justthedesign and randombeautysis to name a few that should get some recognition as well.
